It's a nice image Greg, it would have been a high class amateur photo 20yrs ago! I don't say this as a negative thing but because I used to take astrophoto's thus images like yours take me back to a very fond period in my life ...and so to me this is still pretty dam good really.
Your imaging quality will only improve particularly with the help you are obviosuly getting in your processing form DSLR experienced guys on this forum...you will enjoy the journey I suspect?
